Softer than any other Zoomers fins, the Z2 Zoomers fin is the most comfortable and easiest to use of all the Zoomers fins. With a short blade design, the Z2 Zoomers fin promote a shorter and faster kick for a better workout. The Fluid Separator slices through the water on the down kick, allowing the Hydro Channels to capture more water on the up kick for stronger forward propulsion. The center Flex Box targets and strengthens hamstrings and glutes.
